Abstract
A method of determining the formulating ratio of metallic or pearlescent pigments to colorants for matching the color of a metallic or pearlescent coating to an target color wherein, the spectral reflectances of a plurality of samples varied in the formulation of colorants and metallic or pearlescent pigments are measured with a goniospectrophotometer and stored in a computer memory beforehand and, in performing a CCM using the stored data, reproduction spectral reflectances are calculated by reflecting the changes in spectral reflectance due to changes in the amount of the metallic or pearlescent pigments.
